Alcohol is notorious for high markups, but fountain sodas are also items for which diners often overpay. “We charge $2.50 for a 20-ounce soda,” one owner says. “Even with a free refill, that costs us maybe 20 cents to deliver.” Other profit leaders include pasta, salad, and egg dishes. The best values in entrées: seafood and steak. Sit at the bar. Most restaurant-industry people do that when they eat out. The bartender likely won’t try to peddle all the peripheral items, such as sparkling water, appetizers and desserts, that servers push to pad a check. Plus, you may be more comfortable ordering, say, a smattering of appetizers instead of an entrée. Ask about corkage. Many restaurants will let you bring your own bottle of wine for a fee (typically from $10 at a casual eatery to $50 or more at a high-class restaurant), and some places will uncork your first bottle free. If you drink a Lafite-Rothschild or even a Caymus cabernet, you’ll come out ahead. Note that it’s bad form to bring a bottle that the restaurant already has on its list. And don’t carry in a bottle of bottom-shelf wine or, heaven forbid, a jug.
